Abstract: Aspects of the present disclosure are related to a method performed by a user equipment (UE). The method includes selecting a candidate resource set with a plurality of candidate resources from a resource selection window. The plurality of candidate resources includes a reserved resource that is reserved by at least one other UE. The method includes determining that the reserved resource is associated with a priority level PRX that is higher than a transmission priority level PTX associated with the UE. The method further includes excluding the reserved resource from the candidate resource set based at least in part on the determining.

Abstract: Disclosed are techniques for reducing likelihood of Random Access Channel (RACH) transmission blockages and thereby facilitate an initial access procedure for new radio (NR) unlicensed spectrum (NR-U) operation in a fifth generation (5G) wireless communication system including an NR node. In some embodiments, a parameter generated by a gNB and received by a UE indicates that, from among a set of consecutive RACH Occasions (ROs), a gap is available for performing a listen-before-talk (LBT) procedure before commencing a RACH transmission.

Abstract: Serving cell measurements at a reduced capability UE in idle mode in FRI includes identifying an eDRX cycle length associated with the reduced capability UE is longer than or equal to 20.48 s and shorter than or equal to 10, 485.76 s. The eDRX cycle length includes a DRX cycle length. A measurement period associated with a serving cell of the reduced capability UE is determined to occur within a single PTW of the eDRX cycle. The measurement period includes measurement samples to be performed within the single PTW. A length of the single PTW is determined based on a product of the DRX cycle length and a sample scaling factor associated with the measurement samples. The length of the single PTW comprises a multiple of 1.28. Serving cell measurements are performed during the single PTW. The serving cell measurements include each of the measurement samples associated with the measurement period.

Abstract: Aspects herein relate to wireless devices, circuits, and methods for indicating, by a wireless device, to a wireless station, an ability to support semi-persistent (SP) measurement gap (MG) configuration; receiving, from the wireless station, a SP MG configuration; receiving, from the wireless station, a message to activate the SP MG configuration; performing, in response to receiving the message to activate the SP MG configuration, a target carrier frequency measurement, wherein the target carrier frequency measurement is performed in accordance with the activated SP MG configuration; receiving from the wireless station, a message to deactivate the SP MG configuration; and discontinuing, in response to receiving the message to deactivate the SP MG configuration, the performance of the target carrier frequency measurement. In other aspects, the wireless device may indicate, to the wireless station, an ability to support aperiodic (AP) MG configuration, which does not require explicit deactivation by the wireless station.

Abstract: Provided is a method for a user equipment. The method includes starting performing a handover (HO) with a target Primary Secondary Cell (PSCell) in response to receiving an HO command instructing the HO with the target PSCell, wherein the HO with the target PSCell comprises target PSCell addition/change, and performing the target PSCell addition/change in response to receiving a trigger message from a target Primary Cell (PCell) or sending a trigger message to the target PCell, wherein the trigger message is a message transmitted between the UE and the target PCell during the HO with the target PSCell.

Abstract: The present application relates to devices and components including apparatus, systems, and methods to perform measurements on reference signals based on measurement gaps. In an example, a device supports a frequency range that includes frequencies equal to or larger than 52.6 GHz. Measurement gap capability information is used to indicate and/or determine whether a measurement gap is supported for this frequency range. If so, measurement gap configuration can be defined and can include a measurement gap length and/or a measurement gap repetition period defined based on the frequencies being equal to or larger than 52.6 GHz.

Abstract: Apparatuses, systems, and methods for PDCCH enhancements for group-based paging indications. A user equipment device may be configured to receive, from a network, an indication of a paging occasion via a PG-RNTI and/or via at least 6 bits of a DCI. A value of the PG-RNTI may be associated with the paging occasion as well as a set of UEs, including the UE. The UE may be configured to monitor the paging occasion based on the value of the PG-RNTI and receive, during the paging occasion, a paging indication via at least six bits of a DCI, where each bit of the at least six bits may indicate a paging indication for a particular set of UEs and the particular set of UEs may be a subset of the set of UEs. The UE may also be configured to, in response to determining that the UE has a paging message, decode a corresponding PDSCH.

Abstract: Some embodiments include an apparatus, method, and computer program product for enhanced Hybrid Automatic Repeat Request (HARQ)-ACK in a fifth generation (5G) wireless communications system. A user equipment (UE) can receive, during a HARQ-ACK window, a semi-persistent scheduling (SPS) Physical Downlink Shared Channel (PDSCH) transmission or a Physical Downlink Control Channel (PDCCH) transmission corresponding to a SPS PDSCH release. The UE can generate a Hybrid Automatic Repeat Request (HARQ)-ACK information bit corresponding to the reception. The UE can be configured with an offset value, k, and a length, l, of the HARQ-ACK window associated with an uplink transmission slot n, of a Physical Uplink Control Channel (PUCCH) transmission, and determine a starting slot of the HARQ-ACK window as n-k. When a corresponding valid uplink transmission slot is not available, the UE can transmit the HARQ-ACK information bit in the uplink transmission slot n of the PUCCH transmission.
